UI Consistency with O356
Please Please Please establish some UI consistency with other O365 Apps and services. If you are going to use the toaster use it everywhere. If you are going to use the Hamburger, use it everywhere. If you use the Hamburger, make it always do the same thing.
Please..... I know you acquire and integrate new services very quickly, but inside the MS Eco System, UI consistency should be a primary concern to reduce time to learn.
